IMIRO'V'ED WIRE-TWISTING MACHINE.

TO TALL WHOM IT MAY CON CERN:

Be it known that I, CARL SuoRTAU, of the city, county, and State of New York, have invented a new and improved Machine for lwisting Metallic Wires or Bands; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, refcrencebeing had to the accompanying drawings, forming part of this specification.

The present invention relates to a machine for imparting a twist to metallic wires or bands, and is intended more especially for use in connection with metallic bands employed in the manufacture of that class. of hats known as the Resorte Hats," the invention consisting in a novel and simple manner of imparting such twist to the bands, by means of meehanicaldevices, as will be hereinafter fully described, reference being had to the accompanying plate of drawings, in which- Figure 1 is a plan or top view of the machine, and

Figure 2-a transverse vertical section taken in the plane of the line n: x, iig. 1.

Similar letters of'rei'erence indicate like parts. I

A, in the drawings, represents the framcivork of the machine, which consists of a bed-piece, B,supported at each end upon parallel u prights C. D and E, nprights or standards secured to upper side of bed-piece B 4at each end and at the centre ofthe same respectively, the three being suitably formed to grasp andhold a metal wire or band, it; stretched fronrone end upright to the other, both at its ends and centre. Upon each side of the centre upright E, and intermediate between it and the end-uprights, puppets, or standards Gr are secured to the upperfpside of bed-piece B. II, pinion or geai-n'heels, hung in the upper end of puppets G, so as to freely turn; and I, sector-shaped gear-wheels, attached to a horizontal rock-shaft, J, hung in bearings of the' posts K of the bed-piece, which sector-gears interlock er engage with the pinion-wheels II. L, a crankearm, secured to rock-shaft .Li to the outer end of which -is hunga connecting-rod or wire, M, that, at its lonercnd, is fastened to a treadle-leven'N, hung to the framework A below the bed-piece B, and in suitable position for being worked or operated bythe foot. O, a'spiral spring, secured at one end to crank-arm P of rock-shaft, and atits other fastened to the bed-piece Bf--this spring being provided to throwback the rock-shaft, after having been turned or `operated by vdepressing the treadle-lever N. The pinion er gear-wheels I-I are slotted in radial lines with their centres for the purpose of receiving the bands'tretohed across from one end-upright to the other, as shorvn inthe drawings. l

A'metal band having been stretched across from one end-upright to the other. of the bed-piece, and therein secured in connection with the centre-upright and slotted pinions, if then the trcadle be depressed; the pinions will be made to revolve through the sector-shaped gear interlocking with them, and thus to necessarily twist the band. The band is then taken ont, after which, releasing the foot from the trcadle, the pinions are thrown back to their original po'sitions.

I claim as new, and desire to secure by Letters Patent- The construction and arrangement of the slotted standards D, and standards G upon the bed-piece B, slotted pinions II, sector-shaped gear-wheels I, attached to the rock-shaft J hung in bearings K, erank-arms L P, spring O, wirelM, and trcadlcN, substantially as described for the purpose specified.

The above specification of my invention signed by me this twenty-seventh day of November, A. D. 1866.
